如何关闭点击浮动动作按钮时的片段

Question

我正试图实施一个晶圆厂动作，当一旦点击开始一个片段，并再次触摸关闭片段。我怎样才能做到这一点。

这是我的代码：

final FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      /*Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
        .setAction("Action", null).show();*/ 

      NewOrdersFragment newOrdersFragment = new NewOrdersFragment(); 

      if(isOpen){ 
       fab.startAnimation(FabRanticlockwise); 
       FragmentManager orderManager = getSupportFragmentManager(); 
       orderManager.beginTransaction().remove(newOrdersFragment); 
       isOpen = false; 
      } 

      else{ 
       fab.startAnimation(FabRClockwise); 
       FragmentManager orderManager = getSupportFragmentManager(); 
       orderManager.beginTransaction().replace(R.id.content_buyer_main_area, newOrdersFragment).commit(); 
       isOpen = true; 
      } 
     } 
    }); 

Answer 1

beginTransaction().remove(yourFragment) 

或

beginTransaction().detatch(yourFragment) 

时很方便，你的情况。
